Nqe lus piav qhia
L-Pyrrolidone Carboxy Sodium (L-PCA-Na) yog lub hauv paus tseem ceeb hauv cov tawv nqaij ntawm cov tawv nqaij thiab ib qho ntawm cov yam tseem ceeb ua kom lub cev noo.L-pyrrolidone zinc carboxylate (PCA-Zn)hloov cov sodium ions nrog cov tshuaj tua kab mob zinc ions, thiab tib lub sijhawm muab cov tawv nqaij nrog cov nyhuv moisturizing thiab cov tshuaj tua kab mob zoo heev. Muaj ntau qhov kev tshawb fawb tshawb fawb tau qhia tias zinc tuaj yeem txo qhov tso pa ntau dhau ntawm sebum los ntawm inhibiting 5-reductase. Kev ntxiv zinc rau ntawm daim tawv nqaij pab tswj kev ua haujlwm ntawm cov tawv nqaij ib txwm, vim tias kev sib txuas ntawm DNA, kev faib cell, kev sib txuas ntawm cov protein thiab kev ua haujlwm ntawm ntau cov enzymes hauv tib neeg cov nqaij yog sib cais los ntawm zinc.
